Specification of Letters Patent Patented Dec. 17, 1907.

Application filed Febr le-1y 28. 1907. ..Seria.l No. 359.793.

To all gv'hom it may concern:

Be it known that I, ABNER HARVEY GRAGG, a citizen of the United States,re-

siding at Knoxville, in the county. of Knox 'and State of Tennessee,have invented a new and useful Improvement in a Churn, of

which the following is a specification.

This invention relates to churns and more articularly to reciprocatingchurns; the obect being to provlde a churnwhich is war simple and cheapin construction, and which is very effective in operation.

the a Referring to the drawing A indicates a churn body provided with aremovable top Another object of my invention is. toprovide'a very novelmechanism for reciprocate in the blades alternately.

invention consists in the novel features of construction, combinationand arrangement of the arts hereinafter fully described and pointefoutintheclaims.

In the drawing forming a part of this specification:Figure 1 is avertical sectional viewthrough thechurn. Fig. 2 is a side elevationalview of the churn. Fi 3 is a section taken on the lines 33 of ig. 1.Fig. 4 is a top plan view of the churn. Fig.5 is a pers pcgive view ofone of the-rods carrying a es.

B, on which are mounted the flan ed ends of U-sha ed frames 0 and D,whic are connecte together at one end, by a bar E having flanged ends.Angle-bars F and G are connected to the opposite ends of the reciprocating frames having angled ends, which are connected to the bar E,and the frames are connected together at said ends by a bar One end ofthe bar G rojects out beyond the frame C having a oss G, formed on its.end,'in which is mounted a shaft H car a gear-wheel H provided with ahandle I1 by means of which it'is turned.

Mounted on a shaft I between the bars F and G, is a gear-wheel I whichmeshes with.

the gear-wheel H, and a gear-wheel J secured on a shaft Kwhich is alsomounted be tween the bars F and G, and is provided with crank-arms K, Kat their ends. Wrist pins are secured inthe end of the crank-arms iththese and other objects in view', the

on which are mounted pitman rods L and M provided with an'gled aperturedends.

A central 0 emng is formed in the top B in which wor s a hollow shaft Nprovided 'with an outwardl projecting pin N at its upper end, onw ich issecured the apertured ends of the'pitman rod L, by a nut N The lower"end of the shaft isprovided with a flange M having oppositely disposedopenings formed'therein, in. which are secured the threaded ends of rods'0, by nuts 0 whichvare provided with spaced horizontal blades 0 formingheaters, The depending end ofthe pitman rod M is secured on a pin\ Pprog ecting out from the upper end of a shaft by a nut P and extendsdown through the shaft N having an enlarged lower end P provided withavertical bore in which works a uide-pin Q projecting up centrally fromthe ottom of thechurn body, so that the shaft will be held centrally inthe churn, which reciprocated. Oppositely disposed horizontal blades Pproject-out from the shaft Pwhich are so arranged that when the bladesarereciprocated, they work in between the blades 0 Staples R pro'ect outfrom the enlarged end P of the ro P, and embrace the-rods and preventthe same from spreading. p

Having-thus fully described my invention, what I claim as new and desireto secureby Letters Patent is 1. In a churn, the combination with a-.body provided with a removable top, of frames mounted on said top, ashaft mounted in said frame provided with crank-arms, pitman rodscarried by said crank-arms, a hollow shaft carried by one of said-pitmanrods, working through an opening in the said top, rods carried by saidshaft, provided with a series of spaced blades, a shaft carried by theother pitman rod provided with a series of spaced blades, and means foroperatin said crank-shaft. 2. In a churn, the combination with a bodyprovided with a removable top, of frames mounted on said top, a gearwheel mounted on said frame provided with a handle, a gear meshing withsaid gear mounted in the frame, a shaft mounted in theframe 2 ammocarrying a gear meshing with said gear, I provided with blades, andprovided with a crank arms carried by said. shaft, pitm'an bore in itsand working over a guide-pin rods carried by said crank-arms, a hollowprojecting up from the bottom of the churn. 10

shaft carried: byione of said pit'men extend- ABNER HARVEY GRAGG. ingthrough said top, Carrying rods provided Witnesses:

with blados, and a shaft carried by the other M. M. CQPENHAVER, pitmanworking through the hollow shaft l S. D. TUTTLE.
